These Vacuum Wine Stoppers are used in combination with the Vacuum Wine Saver, sold separately. The Wine Saver is a vacuum pump, which extracts the air from an opened bottle and re-seals it with the reusable rubber Vacuum Wine Stopper. Place the reusable stopper in the bottle and extract the air from the bottle using the Wine Saver pump. The vacuum slows down the oxidation process which makes it possible to enjoy your wine again on a later date.
